This invention relates to window screens and with regard to itsmorespeeificffeatures CO'WlIlClOW screens adapted to cover an irreglilarshaped opening.

An object of th is invention'is to provide an adjustable 'window screenadapted to cover a semi-cireular shaped opening.

A further obj eet of the invention is to pro vide a device of thecharacter described having louvres which may be moved from'a position toscreen the opening to position such as will permit the passage of lightand A furtheroobject of the invention is to provide a device of thecharaeter'described which will be c simple in construction, economicalin manufacture and eflieient in operation.

This may be made by bending the material of one side of the frameupwardly to form the pivot and attaching the material of the other sidethereto to form a shoulder; or the frame may have its top memberintegral and the pivot may comprise a short tubular portion fitting overthe top member and carrying the pivot. This short member may be fastenedto the top member in any suitable manner as by being crimped thereon.The pivots and 17 are co-axial with each other and may, as in theillustration, be

I disposed on the center line of the louver.

Means are provided for oscillating, or rotating all of the louvers ontheir pivotal axes in unison comprising, as illustrated, an arcuatemember 19 substantially concentric with the members 3 and 4. connectedwith a corresponding portion of each louver not on the axis of thepivot, so as to move toward and from the frame member 1, and occupy aplane concentric to it when the screen is closed. As illustrated, theframe 10 is provided at one corner with an eye 20and passing through theeye 20 and connecting the eye pivotally with the member 19 is a loop orlink 21. A suitable cord may be provided for operating the member.terial through for the supports as shown in Fig. 3.

19, which will preferably be attached to the next louver to the end. sothat the cord will not interfere with the complete closing of thescreen.

In order to avoid interference between the members 11 of adjacentlouvers, each alternate louver may have its neck 14 longer than the neckof the adjacent louvers whereby the inner ends of these alternatelouvers will be spaced sufficiently from the center of the member 4 andalternately terminate at different distances therefrom so that themembers 11 of adjacent louvers do not interfere with each other.

Each of the frames 10 may be covered with any suitable sheet materialsuch as glass, metal or wood, but a convenient mafor the purposecomprises cotton duck, which may be sewed to the framework as well as tothe pivot members openings in the latter. To strengthen the louver theframe may be braced by a tie wire 20. y

The lower channel member 2 may be of sufiicient width to serve not onlyas support for the member 4, but also as a track of a lower screen ordrapery This lower screen may comprise a plurality of flexible louvers25 each attached to blocks 26 at its ends, and provided with members 27at its center. Each of these blocks may be attached to rigid verticalmembers 28 at both front and back.

A rectangular rod 29 may extend parallel to the channel 2, and havemounted thereon for horizontal but not rotative movement brackets 30, tothe front and back of which the ends of the members 28 may be connected,whereby when the rod is rotated the slats are rotated with the rod toopen or close the screen.

The brackets 30 may have supporting arms as shOWn at 32, carryinganti-friction rolls 33 which may engage a flange 34 of the channel 2 tosupport the screen from the channel 2.

Operating cords as 35 may be attached to the brackets 30 by which theymay be moved horizontally to collapse the collapsible louvers and removethe screen from before the opening.

A latch as 36 may be provided for holding the vertical members inextended position.

By this construction, by pulling on the cord 85, the vertical membersatone side will be moved longitudinally of the channel whereby thescreen will be removed from before the opening.

Means are also provided for coverin the central space around the members4' an the pivot members 11, which may take the form of a rosette, asshown in Fig. 1.

The manipulation of the screen will be obvious from the description ofits construction. By the movement of the member 19, all of the louverswill be simultaneously rotated each about its pivot whereby the louversmay be all brought substantially into the plane of the frame 1 or may bemoved to a position perpendicular to that plane thus eithersubstantially wholly excluding the passage of air and light through thescreen or freely permitting such passage.

Thus by the above construction are accomplished among others the objectshereinbefore set forth.

As many changes could be made in the above construction and manyapparently widely different embodiments of this in vention could be madewithout departing from the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanying drawingsshall be interpreted as illustrative and'not in a limiting sense.

It is also to be understood that the language used in the followingclaims is intended to cover all of the generic and specific features ofthe invention herein described, and all statements of the scope of theinvention, which, as the matter of langua e, might be said to falltherebetween.

H aving described my invention what I claim as new and desire to secureby Letters Patent is 1. A window screen comprising, in combi nation, asemi-circular frame, a plurality of radially disposed slats pivoted inthe frame on radially disposed pivots, a semi-circular member and meansfor connecting the end of each slat distant from its pivotal center withsaid semi-circular member. 2. A window screen including, in combination,a plurality of slats, pivot members having slat engaging portionspivotally supporting said slats, adjacent slat engaging portions of saidpivot members being relatively offset so as to avoid interference in theoperation thereof.

8. A window screen comprising, in combination, a plurality of radiallydisposed slats, each slat being provided with apivot member on the endtowards the center, adj acent ones ofsaid pivot members having'slotholding portions disposed at difi'erent distances from the center.

4. A window screen comprising, in combination, a substantially U-shapedframe provided at one end with a pivot member and at its other end witha pivot member comprising a block in the plane of the screen into whichboth of the free ends of the U- shaped frame are fixed.

5. A window screen bination, a substantially U-shaped frame provided atone end with a .pivot member and at its other end with a shaped frameare fixed, and sheet material attached to said frame and lying in theplane joining the legs of the U-shaped frame.

plane of the screen into which both of the free ends of the U-shapedframe are fixed,

comprising, in compivot member i into which both of the free ends of theU--' said blocks being staggered to avoid inter ference between adjacentslats.

7. A screen comprisin'g,in combination, a frame comprising two members,

a plurality ofslats pivoted to said members and .oscillatable to openand close the screen, theoscillatory axes of said slats concentricarcuatebeing generally radially arranged relative frame comprising twoconcentric arcuate members, a plurality of-slats pivoted to said 7members and oscillatableto open and close the screen, the oscillatoryaxes of said slats being generally radially arranged relative to eachother, said slatstapering toward said inner'arcuat member, andalternately terminatingat different distances therefrom, and an arcuatescreen operating member piv otally connected to said slats and movableto and from said frame, said screen operating member being in a planeconcentric to said arcuate frame members when the screen is closeda q"9. A screen comprising, in combination, a frame having concentricallymounted flanged arcuate members, and a straight member having anupstanding stiffening flangeserving as a track fora roller, and slatsmovably mounted in said arcuate members,
